However I feel a lot of the article and many of your posts about it in here come down to "it makes me feel uncomfortable" which.. I mean, ok. Sure. I hate spaces for indentation and think double quotes are better (and I have reasons for both)... but I don't say there's no use to the other options.
I feel you're throwing the baby out with the bathwater here.
Should const probably have been about value immutability too? Yes, I think so. I totally agree. That's a REALLY important topic to discuss. Maybe pitch it to the ES2016 committee as an iterative upgrade to const?
But as it stands it does have value. Yes it mostly just codifies what programmers original did as a language construct but it does also stop redefinitions which was an annoyingly common issue. So it's progress. Small, incremental, and not as full-featured as we'd both like... but it's progress.
Drawing attention to the issues with const is important... but there's no reason to rail so hard against its usage when it's understood to have those limitations... is there?
